To all whom 2'25 may concern:

Be it known that I, CLARENCE E. FALon, a citizen oi? the United States, residin Akron, in the county of Summit and tate of Ohio, have invented new and useful Improvernents in Infiating-Tube Protectors, of which the following is a specification.

This invention relates to a device for protecting the tube used for conducting an inflirting fluid to an inflatable body such as a pneumatic tire.

.As now constructed, pneumatic tires are rovided with a short rubber infiatin -tube ror conducting'the inflating fluid to t e interior of the tire, and which is usually passed through an aperture in the rim on which the tire is mounted, which makes it easily torn from 1 the tire when said tire shifts its position on the rim for any reason. The ob ect of this invention therefore, is to' provide a suitable device of ii 'd material which can be connected with te tire to receive the inflating tube and project through the aperture in the rim which will prevent the shifting of the tire and the consequent tearing or destruction of the inflating-tube. A further objectis to so construct the device that it does not in any way im air the tire or render its construction in t e ordinary way difficult and which when mounted in connection with the tire rim will project through the aperture therein to receive a clamping nut for clamping the tire securely to the rim, 7

With the foregoing and other-objects in view, the invention consists in the novel construct-ion, combination and arrangement of arts constituting the invention to be herematter specifically described and illustrated in the accompanying drawings which form a part hereof wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope ofthe claims hereunto appended. v

In the drawin s in which similar reference numerals in icate like arts in the diferent figures, Figuresil an 2, are views in side elevation of my improved inflatin -tube protector; Fig. 3, is a view of an or inar inflating-tube detached from a tire; an Fig. 4, 1s a transverse sectional view of so much of a tire as will illustrate the application of this invention. to a tire, showing the same in operative connection with the inflating-tube. I

\ Referring to the drawings the reference numeral ldenotes generally the inflatingtuhe protector which consists of a tubular stem the upper end 20f which is of comparatively thin malleable material, preferably metal, below which and integral-therewith is a thicker portion 3 providedwith exterior threads 0. Below the threaded portion 3 is a hub 4 terminating at its lower end in an elliptical thin flange 5, which is bent or curved as shown in the drawings-with a curvature approxim'atelylthe curvature of the tire with which it is to be used. The bore or interior diameter of the protector is suficiently large to receive the tu ing-tube and which is customarily provlded at its lower end with a radial flan e 7 prefcomparatively fine mesh;

ular portion 6 of an inflat In assembling the tire in connection with my-improved rotector the tire is set up somewhat as pecially directed to Fig. i in which the reference numeral 9 denotes'the inner airsi v ollows, attention being es-,

pontaining tube of the tire which is provided 1 with an openingI 10. The inflating-whet;v posit-ione on t and the flange 7 surrounds the opening'and e tire so that the opening 1n the tube 6 registers with the openurg jltl' .is cemented to the tube 9. The inner tnhetl 'tis then inclosed ina wear-resisting layer of an opening through which the tube. 8 projects. The protector 1 is then slipped over the tube 6 with its flanged lower end 3- shaped to coincide with the curvature of the tire and with its threaded endprojecting outwardly. The tire is then built, up pi a plurality of la. ers of suitable materiel L suitable material llwhich is provide with 13, and 14, an more, if necessary, suficient layers being employed to secure the desired strength in the tire. As before stated the exterior diameter ot the inflating tuhe'fia-is approximately the same as'the interior diameter' of protector 1 so as to leave little or 'nospaee between the two as is clearly shown in Fig.- 4, and it will be noted that the flanged portionb of the protecting mem- 5 bar 1 is securely anchored within the wall of the tire and held thereby the strengthgiving plies of material 12, 13 and 14 so as to'therehy unite thefiprotector-J firmly with the tire-body. The next step in" assembling is to insert in the open'endtof thatube 6 which customarily projects beyond the; open end of the member I the shanlrend' 15 0f a valve-stem which-is usually ofa sufli cient, ,diameter to distort the rubber of the'tube-fi,

15 and crowd it against the inner wall of the member 1 with considerable force. stem is usually provided with, a plurality of circumfiu ential ribs 16" for more securely I anchoring the shank end-15 in place, after which the orti'on 2 of the protecting member 1 whic is made of malleable material is pinched or squeezed inwardly, or-otherwise'contracted so .as to compress the rubber tub'e 6 firmly against the shank end 15 2 of the valve-stem. The tire is then mounted on a wheel rim with the protecting mem: her 1 projecting through the usual aperture in the rim provided for this purpose. The nut 8 is then a plied and rotated so asto draw the tire Trmly a ainst the rim and hold the same against s ifting. The usual cap 17 is then applied to the outer threaded end 18 of the valve-stem and the device is ready for use. I

It will be noted that by embeddin the flanged end 5 of the protecting mcm r 1 within the wall 10f the tire and gassing the stem portion of the protector t rough the opening, shifting of the tireis prevented and consequently the danger of a shearing action between the rim and the tire. tending iniure the comparatively deli;
